| Feature | Specification |
|---|---|
| Engine Model | Cummins NT855-C450 |
| Configuration | In-line 6 Cylinder, 4-Stroke Diesel |
| Displacement | 14.0 L (855 cubic inches) |
| Rated Power | 336 kW (450 HP) @ 2100 RPM |
| Peak Torque | High torque output, characteristic of the NT855 platform |
| Aspiration | Turbocharged & Aftercooled |
| Fuel System | Cummins PT (Pressure-Time) Direct Injection |
| Emissions | Industrial Specification |
The NT855-C450 is designed as a prime power source for heavy machinery and equipment where high power density and 24/7 reliability are critical.
Heavy Construction & Mining: Powers large excavators, bulldozers, wheel loaders, and mining trucks that require immense torque and resilience in rugged environments.
Power Generation: Serves as a highly reliable driver for large-capacity industrial generator sets, providing prime or standby power for data centers, manufacturing plants, and utility support.
Industrial Drives: Ideal for high-capacity pumps, compressors, crushers, and other industrial machinery requiring continuous, high-power operation.
Marine & Specialized Applications: Used in marine auxiliary power and other specialized heavy equipment.
1. Legendary PT Fuel System for Ultimate Reliability
At the heart of the engine is the fully mechanical Cummins PT (Pressure-Time) fuel system. Celebrated for its simplicity and robustness, this system provides precise, gear-driven fuel metering. It ensures optimal combustion, excellent throttle response, and reliable operation even with varying fuel qualities, minimizing downtime and simplifying maintenance.
2. Advanced Turbocharged & Aftercooled Performance
The engine features an efficient turbocharged and aftercooled (TTA) aspiration system. This technology forces a greater mass of cool, dense air into the combustion chambers, significantly increasing power output and improving combustion efficiency. The result is superior fuel economy, lower emissions, and reduced thermal stress on engine components for extended life.
3. Durable Heavy-Duty Construction
Built for longevity, the NT855-C450 incorporates a rugged cast-iron cylinder block and replaceable wet cylinder liners. This design ensures excellent heat dissipation and allows for straightforward in-frame overhauls, dramatically extending the engine's service life and reducing the total cost of ownership.
